Product Summary
The MK48Z02B-25 is a 16384-bit, non-volatile static RAM. The device is organized 2K×8 using CMOS and an integral lithium energy source. The MK48Z02B-25 has the characteristics of a CMOS static RAM, with teh important added benefit of data being retained in the absence of power. Data retention current is so small that a miniature lithium cell contained within the package provides an en-ergy source to preseve data. Low current drain of the MK48Z02B-25 has been attained by the use of a full CMOS memory cell, novel analog support circuity, and carefully controlled junction leakage by an all implanted CMOS process.
